What is the south carolina sales tax calculator?
In short
In South Carolina, the state sales-tax rate is 6% (average combined 7.49% with local add-ons). Expect $6.00 of state tax on a $100 item — $106.00 all in. South Carolina pairs its 6% state rate with county local-option taxes up to 3% (combined rates reach 9% in Charleston), so the total at the register varies meaningfully from county to county.
This calculator applies South Carolina's 6% state base rate to any price and shows the tax and total instantly. Because Columbia and other localities can differ, it also lets you enter your exact combined rate. South Carolina exempts groceries from the state tax but lets counties apply local-option taxes to food, so groceries aren't always tax-free.

Worked example
The scenario
A $500 purchase in Columbia, South Carolina, where the combined rate is 8%.
The result
At the 6% state base rate the state tax is $30.00 ($530.00 total); at Columbia's 8% combined rate you'd pay more once local tax is added.
Common use cases
- Estimating the out-the-door cost of a South Carolina purchase before you buy
- Comparing tax on a big-ticket item between Columbia (8%) and a lower-rate locality
- Seeing why your receipt differs from the 6% headline — the state runs an annual August 'Tax-Free Weekend' that exempts clothing, computers and school supplies.
- local-option rates are reset annually, with most changes taking effect on May 1
Limitations & assumptions
- This tool uses the South Carolina state base rate (6%); combined local rates vary — county local-option taxes up to 3% (combined rates reach 9% in Charleston).
- Unprepared food is exempt from the 6% state tax but still subject to local-option taxes (commonly ~1%), so groceries are not always fully tax-free; prepared food is fully taxable.
- Confirm the current rate with the South Carolina Department of Revenue before filing — local rates change often.
- This is a budgeting estimate, not formal tax advice.
